A link, in this context, is not just any hyperlink. It is a contextual, dofollow (or strategically nofollow) link that connects the Naberblog property to your main money site, your email autoresponder, or directly to the ebook download. Without the link, the ebook sits in isolation. Without the ebook, the link has no value to offer the user.
Many such blog links become dead after a few months due to DMCA takedowns. If you encounter a 404 error or empty folder, the link is likely removed. ebook naberblog link
